Scott Brawner was working out at a Clackamas health club when he received an alert. He used the map on the app and found Drew Basse in a parking lot. He immediately started CPR on the 57-year-old man and continued until paramedics arrived.

Brawner has saved hundreds of people with CPR, but since this was a different case, he visited Basse in the hospital.

"One of the first things he said was, 'I was dead. You saved my life. I owe you,'" Brawner recalled. "I said, 'You owe your family to get better. You don't owe me anything.'"

PulsePoint is designed to be used be regular citizens too, so they can be heroes as well. After someone calls 911, the app uses location-based services to direct citizen rescuers to the exact location, and also displays where they can find the nearest automated external defibrillator. If you can help, you can go help someone in distress to keep them alive until emergency responders arrive.
